1. An optical packet switching apparatus comprising:
- an optical switch unit configured to switch a route of an inputted optical packet signal;
an optical signal-to-noise ratio (OSNR) acquiring unit configured to acquire information on an optical signal-to-noise ratio of the optical packet signal; and
a regenerative relay unit configured to regenerate and relay the optical packet,wherein, when the optical signal-to-noise ratio of the optical packet signal is less than a predetermined reference value, the optical switch unit outputs the optical packet signal to the regenerative relay unit.

Abstract
An optical packet switching apparatus includes an optical switch unit for switching the route of an optical packet signal, an OSNR acquiring unit for obtaining the information on the optical-to-noise ratio (OSNR) of the optical packet signal, and a regenerative relay unit for regenerating and relaying the optical packet. When the OSNR of the optical packet signal is less than a predetermined reference value, the optical switch unit outputs the optical packet signal to the regenerative relay unit. The regenerative relay unit sends back the regenerated optical packet to a route through which the optical packet is supposed to be sent out.
